Yes, I agree; as with rainbows, I believe that I saw two different
reflected images, one with each eye, and two different "primary" images,
again one with each eye.
In my theory this holds, anyway, in an instantaneous analysis.
In "real time", with each miniscule change in my head's position, I must
have seen yet additional, in principle "different" images. The same is
no doubt true of the movements of the surface of the bay, with each wave
and wavelet causing changes in the angles of reflection. Presumably the
same argument would apply to atmospheric changes that affected the light
paths from the "parahelion" in the ice crystals aloft on their way to my
eyes, and to the constant changes in the positions and orientations of
the individual ice crystals as well.
In other words, an infinity of "perihelia"!
Does this make sense?
Jim

Hi James etc
So you were seeing two different reflections with both eyes. Both eyes
can't
catch the same beams of light can they? And your original "parahelion"
will
be the same, I assume.
Sorry James I didn't phrase the question correctly, my fault.
Is the reflection of Jame's parhelion the same as the original?

That is, each eye sees its own original "parahelion".
Looking at the reflection each eye sees its own reflection.
See what the others say.
What you say about the change in contrast of image in the reflection
makes
sense.
I have noticed that when viewing sundogs and coronas in water surfaces.
Keep up the good work viewing!
Regards
Kevin
